Microstructure and thermal properties of copper matrix composites reinforced by chromium-coated discontinuous graphite fibers

Anisotropic properties of highly textured porous alumina formed from platelets

“…7. When composite materials consisting of a Cu matrix and highly oriented graphite fibers as a reinforcing material were fabricated using the PECS method, the variation in the thermal conductivity of a single body with respect to measurement direction could also be a factor of two [25]. However, the porous alumina sample with highly oriented grains was fabricated from a monolithic material, so the observed difference in thermal conductivity with respect to direction is thought to be unique, since porous alumina with highly direction-sensitive thermal conductivity and a bending strength of more than 200 MPa has hitherto not been fabricated.…”

Promising metal matrix composites (TiC/Ni–Cr) for intermediate-temperature solid oxide fuel cell (SOFC) interconnect applications

“…The experimental CTE of composite is lower than the calculated value based on the rule of mixture (9.66 Â 10 À6°CÀ1 ), Turner model (9.28 Â 10 À6°CÀ1 ) and Kerner model (9.79 Â 10 À6°CÀ1 ) [7,10]. The special low CTE may be attributed to the strong interface bonding [30] and partial connected particles [31], which both restrain the deformation of metal matrix. Therefore, the CTE of C-276 can be lowered by the introduction of appropriate content of TiC to meet the requirement of SOFC interconnect applications.…”

Effects of Zr-Cu Alloy Powder on Microstructure and Properties of Cu Matrix Composite with Highly-Aligned Flake Graphite

“…Graphite reinforced copper composites have attracted wide attention as potential thermal management materials due to their high thermal performance [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. Graphite materials used as thermally conductive fillers commonly include graphite fiber, flake graphite (FG), and graphite film [ 4 , 5 , 6 , 12 , 13 , 14 , 15 , 16 , 17 ]. Flake graphite/copper (FG/Cu) composites have good TC (397 W∙m −1 ∙K −1 ) and mechanical properties of Cu, as well as ultra-high TC (1500 W∙m −1 ∙K −1 ), low density, low CTE (−1.0 × 10 −6 K −1 [ 18 ]), and good workability of FG [ 19 , 20 ].…”

“…To solve the above problems, two prevalent approaches of matrix alloying and coatings on carbon surface have been carried out [ 9 , 10 , 15 , 16 , 17 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. Matrix alloying was often used in liquid infiltration.…”
